Mini-SD wifi and memory in one card?

Has anyone heard of a mini-SD with wifi and available memory? 512 mb or 1 gb. I know that there are wifi/memory cards for standard SD cards and there are mini-SD wifi cards but I can't find any mini-SD wifi cards with memory. This would be really helpful for the treo 750. It would make it much easier to switch from my 8525 that has all that built-in. Except for the stupid micro SD card for the 8525. Everything has a catch these days.
